Lean Canvas
Make assumptions visible before investing in the wrong solution.
Begin with the problem and the people
Lean Canvas is a one-page business-model framework created by Ash Maurya, author of Running Lean. It helps teams make assumptions explicit and test them. See Maurya’s official site and his book page.
Nine areas to investigate
| Canvas area | A question for a student team |
|---|---|
| Problem | Which recurring difficulty matters enough to address? |
| Customer segments | Who experiences the problem, who pays, and who approves use? |
| Unique value proposition | What useful improvement would make this solution worth adopting? |
| Solution | What initial approach could address the most important need? |
| Channels | How would users discover, obtain, and receive support for it? |
| Revenue streams | How would a commercial offering earn revenue? |
| Cost structure | What must be spent to develop, deliver, and sustain it? |
| Key metrics | What observations would show progress? |
| Unfair advantage | What defensible asset or capability is difficult to copy? |

Railsware: 5 Lean Canvas Examples offers retrospective illustrations based on familiar businesses. Use them to compare how the canvas connects a problem, customer, solution, and business model; they are reconstructed examples rather than original canvases prepared by those companies.
Applying it to senior design
Consider an illustrative reusable fixture for a small manufacturer. The operator uses it; a supervisor may request it; purchasing approves expenditure; maintenance inherits it. Interviewing only one person may miss important requirements.
Write assumptions as testable statements. For example: “Setup variability accounts for at least ten minutes of lost production per batch.” Observe and measure several batches before designing around that claim. Distinguish a user’s account from measured evidence.
For an internal or community project, commercial revenue may not be the primary objective. Record how the work is funded and maintained in an accompanying project brief, while acknowledging that this extends the business-model discussion beyond a conventional commercial canvas.
A simple classroom exercise
- Draft the problem, users, and proposed value before discussing detailed features.
- Identify the three assumptions most likely to invalidate the idea.
- Choose a small interview, observation, or experiment for each.
- Record results, contrary evidence, and what changed.
- Translate supported needs into engineering requirements.
Lean Canvas complements the engineering process. It does not establish technical feasibility, satisfy design criteria by itself, or replace safety analysis and verification.

From the business model to funding
Seeking Capital explores funding needs, financing choices, partner perspectives, and the trade-offs involving ownership, control, and direction. Use the canvas to identify the assumptions that funding would help test.
